reverie CUTTING AND FLANGING DEVICE.

Application led August 1,A 1927. V Serial No. 209,976.

This invention relates to cutters, and its general object is to provide a device for cutting an annular opening in metallic drums and the like and rolling the edge of the opening, so as to provide an opening capable of introducing and removing semi-solid materials into and from the drum and to receive a closure which is detachably associated about the opening for closing'the same in na manner whereby a tight joint is provided yet the closure can be removed lin an easy andexpedit-ious manner whenl access to the drum is desired. y

A further object ot the invention is to provide a'means for conditioning oil drums and the like whereby grease can be introduced and housed therein, and dispensed therefrom. Y

Another object of the invention is to provide a cutter including an edge roller, that is simple in construction and inexpensive to manufacture.

This invention also consists in certain other features of construction and in the combination and arrangement ot the several parts, to be hereinafter fully described, 1l-

' lustrated in the accompanying drawingsv and specifically pointedA out in the appended claims.

' ln. describing my invention in detail, reference willV be had to the accompanying drawings wherein like characters'denote like or. corresponding parts throughout the several views, and in which: l

Figure 1' is a bottom plan view ofthe device 4for cutting and rolling the edge of openingsy in metallic drums and the like. U Figure 2 is a sectional viewl taken approximately on line 2 2 o'Figure 1 and show ing the device in operation. l y

Figure 3 isa sectional view taken online 3- -3 of Figure l.

Figure 4t isa detail sectional. Aview illustrating the action of one of the rollers on the edge ot' the opening termed by the cutters.

Figure 5 is a fragmentary transverse sectional view taken through the head of a drum showing a closure fixed to the head and closing the opening ormedby my device.

Figure 6 is a bottom plan View of Figure 5. f

Figure 7 is a sectional 7-7 of Figure'. i

Referring to the drawings in detail it will view taken Von line be noted that my device is adapted to form l' an opening in the head ot' a metallic drum or the like, will'rollthe edgeot the opening so 'as to Jr'orm a flange adapted to receivea closure which is -ixed to the opening in a manner whereby it can" be removed andj so .that greaseand other semi-solid materials can be introduced, housedand dispensed from metallic drums thaty are now generally i commercially used Jfor oil. v

The opening cutter and roller 1s provided with abody 1 `havinga-n opening formed l therein which is `adapted to receive afdrill lshank 2 iixedly secured therein and 'said shank is rprovided 'with ay tapered bore'com'- municating at its upper end vwith a slot 3. The bore is adapted to receive a drill .bit 4:

in the manner as best shown in Figure 2 of the vdrawings and inorder to remove said bit from its bore, a wedge block 5 lmay .be passed intothe slotBt'or engagement with the endof the bit `as shown.

Radiating from the body 1 are a'` plurality of arms, two ot which are indicated by tne reference numeral 6 and are provided with transversely disposed slots 7 to receive the shanks 8 of cutting blades 9. Thecutting blades are adjustably held inrsaidslots l8 through theinstrumentality ot set screws 10. llhe remaining'arms which are indicated by the reference numeral V'11 are .disposed in pairs and have' depending therefrom ad" jacent their ends,v headed pins 12 `which receive yrollers 13 having beveled lower ends lll as shown. The rollers are mounted for rotation on the pins 12 and are spaced from 1 v the under surface of their arms 11 by disk washers 15. 'The heads of the pinsv 12 are indicated by the reference numeral 16 and are tapered to a greater degree' than the bevel oi' the lower ends 1Llot the rollers 13,"I

but have their' outer edges of their upper ends' arranged flush ywith the outer edges ol' the lower ends of the rollers 13 as best shown in Figure 4 of the drawings.

When it is desired to form' an opening in the head of a metallic drum as indicated by the letterA the device isl centrally disposed `with the `head B of the drum and rotated which will result in the bit 4: penetrating the head B to an extent whereby the cutting blades 9 will cut through the head and `provide an opening C ers will then engage the edge of the opening and form a downturned flange D as The roll-` v' 'i rollers engage the edge andfpos'ition .thev vsame to provide the flange.Vv The device is shown in Figure 4, it being obvious that the flanges formed by the beveled portion of the pins and rollersengaging the edge and gradually causing the. edge to be turned inwardly until the fiat portions 17 of the then removed from the opening Which is of sufficient size to introduce grease or other semi-solid materials in the druiii and reinforcing blocks 18 are lixed to the underside v of the head B andai-ranged in contacting ifo :` tions mounted for rotation on some of saidkengagement with theinner side of the flange The reinforcing as shown in Figure .5. j blocks are fixed to the heads through Vthe .medium of rivets 19. Aclosure is provided for the opening and said closure isof course `disk shape iii formation .and is provided with ,a substantially right angle shape flange which vincludes portions 20 and 2l. llhe portion 2O is disposed in fittino engagement with the flange l) and the portion 21 is pro- .tion that the advantages and novel features of my invention will be readily apparent.

`I desire it to be understood that I may make changes in the construction and in the j combination and arrangement the several parts, provided that such changes fall within. the scope of the appended claims,

Vhat. I claim is: y l p 1. A tool for forming langedopenings in metallic receptacles, comprising a body,

ashanlr lixedly secured in saidbody and be ingprovided with a bore, a drillbitdetac-hably ksecured in said bore, arms radiating from said body, rollers having beveled porarms, knife blades adjustably mounted in the remaining arms, and set-screws for retaining said knife blades in their adjusted positions.

2; A tool for forming flanged openings in metallic receptacles, comprising a body having an opening formed therein, a drill shank` formed l'with a tapered bore communicating with a slot arranged therein and said drill shank being secured in said opening otthe'body, a drillbit detachably secured iii said bore, arms radiating from said body, rollers and knife blades carried by said arms adjacent their outer'ends thereol", and said rollers being mounted for rotation andr provided with straight portions vmerging into bevel portions.

3. A tool of the character described coni,- prisinga body, arms radiating from said body,y pins secured to some of said arms and extending Vat right angles therefrom, rollers;`

mounted for rotation on said pins, the remaining arms being provided with slots, knife blades .including shanls An'iouiited for adjustment in said slots, means for lretaining said knife blades in their adjusted posibody .and being detachably secured with respect thereto.l j j .i
